The problem with the Cadfael costuming is that with HiDef TV, you can very much see they just sprayed knitted wool sweaters with silver paint instead of using regular chainmail. Also, couple of zippers and at least one pair of denim jeans can be seen. Stuff you'd get away with on regular tv back in the day, but pretty obvious now.

We do need more TV paced like that, and episodic like that, though. I agree with you there.
